Hi all,We are looking to purchase a new home built by Standard Pacific in Round Rock. The plan is the Sheffield plan, so the livable sqr footage is around ~2250. We were thinking of two AC units for the house since it is two stories. We were told having two units is not necessary since the house has so many energy saving features. It will also have a zoned AC also. It is only the two of us now; we keep the thermostat at 75 in the summer, and the heat at 71. We will have a gas water heater and stove.
Can anyone let us know if the houses are really that energy efficient? Also, if someone would be so kind as to post what the average electric bill would be in the summer and winter in a similar standard pacific home

what kind of energy efficient features do the houses have?

Radiant barrier? Low-E windows? Insulated walls and attic? Where are the inside units located? All of that makes a difference.

The units and ducts need to be properly sized for the space, preferably by an engineer. What is the SEER of the ac units? I would assume that the HVAC for production homes was done at some point by an engineer, I would go with that recommendation.

It can be hard to know exactly what your bills will be even if someone with the exact same house responds. The orientation of the house (minimize western exposure if possible) and the tree cover can make a tremendous difference. Fuel charges and other inputs for the electrical company can change.

See if Standard Pacific has an energy audit of their home available and if they have an green building certification.

I can tell you that when I moved from a 1950s uninsulated bungalow to a three-star green builder house (with six inches of insulation in the walls, low-E windows, sealed ducts, radiant barrier etc) I more than doubled the sq footage of my house but had level or even lower electric bills. Such features do make a real difference.

The house will have radiant barrier roof decking insulated double paned low E windows. R13 in the walls,r22/r30 in the ceilings. I do believe the units will be up in the attic. It will be a 14 SEER unit with puron. The house will be facing West I was told we could get some type of reflective film that you can apply to the windows. We will plant trees where appropriate.
We are in a smaller one story now and the bills are easily managable. We are just trying to get all of our ducks in a row!

We have 2400 sq ft with very similar energy features, (plus CFL in most of the house), last month our electric bill was $31!

I think you will be in good shape. Even in August, I would expect very managable bills. I didn't fully appreciate our homes' energy efficiency until we moved in -- now it is my favorite feature!

good luck!

You can ask them to put extra insulation. Like if you have a room above the garage, good idea to put extra insulation on the garage roof.
Here's a tip, some friends bought their own insulation and put it in before sheet rock. For sound insulation as well. Builders say they don't allow it though.
